Square root 80 = 4 x square root 5
because root 80 = root 16 x root 5
190-(50+80)t=0
190-130t=0
130t=190
t=19/13 so the trains will remain apart for 19/13 hours.
Since ironman is flying at a constant rate of 150mph he will fly:
150(19/13)≈219.23 miles in that time period while the trains are apart.
The answer is b 18. 48 divided by 8 =6 therefor each 8th is 6, 3 8ths of 48 is 3 times 6 which equals 18.
The 1st, 4th, and 5th answers are correct
Answer:
parallel slope = , perpendicular =
Step-by-step explanation:
to find slope, formula:
:
:
if parallel, same slope, so slope = 13/8
if perpendicular, slope = -1/n = -1/13/8 = -8/13 is the perpendicular slope.
